Reference numeral 111 in the drawing denotes a guide portion. FIG. 10 shows an embodiment using a screw jack system, in which two sets or two sets of screw jacks 200 are mounted on the stigmas of the temporary support columns 2 or the like, and screw rods 201 that are raised and lowered by the jacks are provided on each roof. The roof R is pivotally supported by the R beam 202 to move up and down the roof R by the screw jack 200. 203 is a deck plate. The screw jack method is inexpensive and has a proven track record of control methods, and has the advantage of high safety in the event of a power failure, but when the temporary support pillar 2 is moved up and down, high work at the stigmas occurs, and the weight of the temporary support pillar top is large. However, there is a problem such as imbalance. In this respect, if the manipulator is used to raise the temporary support, the screw jack need only be one floor long, and the length of the temporary support is unnecessary. Therefore, it is possible to make the upper part smaller.

The horizontal force applied to the main roof is supported by the reinforcing bars of the main RC columns, but the horizontal force may be borne by reinforcing the main pillar reinforcing bars. In addition, it may be supported on an external scaffold of a building rising from below, or may be supported via an outer scaffold supported by a lower steel beam. Alternatively, it may be supported by pulling it from the upper frame with a wire or the like, and the wire may be stretched in response to the rise of the main roof.

Furthermore, by suspending a simple scaffold on the outer periphery of the frame, it is possible to realize a non-scaffolding method without being restricted by conditions such as building location conditions and external shape.
The construction cost is reduced, the construction period is shortened, and the safety is improved in combination with the conventional structure in which the temporary opening is not provided inside the structure. Furthermore, in the case of a high-rise building, a large-sized tower crane can be omitted by equipping the rooftop with a crane installed on the roof, thus reducing the construction cost.
